Ultrasound-guided versus traditional surgical resection of supratentorial gliomas in a limited-resources neurosurgical setting

Background Intraoperative ultrasonography (IOUS) represents a cheap and safe alternative to the more expensive intraoperative guidance modalities. In this study, we investigate the impact of introducing IOUS in the surgical management of supratentorial gliomas and compare its use objectively to unguided surgery.
